IMPROVEMENT IN DOOR WEATHER-STRIPS.

Specificationv forming part of Letters Patent No. 39,@7S, :latedSeptember 15, 1863.

To all whom it may concern:

Beit known that I, B. WV. BOYGE, of Lansing, in the county of Ingham andState of Michigan, have invented a new and useful Improvement inWeather-Strips for Doors; and l do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawings, which forni a pai-t oi' this specication, and ofwhich- Figure l is a view in isometrical perspective ot' a door-frameand door with my improved weather-strip attached thereto; Fig. 2, afront elevation of the same; Fig. 3, a vertical seetion in the line x auof Fig. 2, showing the manner in which the strip is pressed down andclosed upon the door-sill; Fig. 4, a vertical section in the line y y ofFig. 2, showing the position and arrangement of the spring placedbeneath the strip; Fig. 5, a bottom view of the edge of the door, withmy improved strip attached thereto; and Fig. 6 is a vertical section inthe line z z of Fig. 5, showing the form of the recess formed in thedoor for the reception of the upper edge of the vibrating strip.

Similar letters indicate like parts in each of the drawings.

M yimproved weath er-stri p consists, mainly, of a single piece, A,Figs.` 1 and 2, of wood or metal, (l prefer metal,) molded into the formillustrated in the accompanying drawings, (see the sections thereof,Figs. 4 and 6,) or' such other shape as will admit of proper attachmentto the door and attain the result sought for in my invention. Inattaching this strip A to the door B, I first cut out a rabbet orrecess, c, Fig. 6, in the latter at a proper distance above its loweredge to receive the upper edge of the vibrating strip A, which may behinged thereto very quickly and simply by means of two or more staples,b b, Fig. 2, which embrace a wire secured longitudinally in or along theupper edge of the strip.

there it is preferable, butts or other forms of hinges may besubstituted for the device above described.

To keep the vibrating strip up above the reach of any obstructions whenthe door is open, I place and secure one or more suitable springs, C,Figs. 4. and 5, beneath the strips A, and between it and the door B. Andin order to overcome the resistance of' such springs and to force andclose down-the strip upon the door-sill so as to make a tight joint whenthe door is shut, I form an inwardly-projecting arm or tooth, c, Figs. 3and 5, upon the inner side ot" the vibrating strip A, a few inches fromits inner end, the recess in the door being enlarged at this point, asshown in Fig. 5, to receive it when the door is closed. This projectionc serves as one arm of an angular lever, ot' which the lower edge of thevibrating strip A would form the other, as shown in Fig. 3. A tooth orlug, d, Fig. l, is secured to the door-sill D in such a position as tostrike the arm @when the door is closed, and by pushing it inward andupward causes it to force the lower edge ot' the vibrating stripdownward closely upon the threshold of the door. The lug d may be castof metal and secured to the sill D by means of screws, as is clearlyshown in Fig. l; or it may be arranged in any other suitable manner incombination therewith, care being taken that it shall be placed withinthe sweep or circumference of anr imaginary circle, e, Fig. l, describedby the inner lower corner ot' the vibratin g strip A, as the door B, towhich it is attached, turns upon its hinges.

To perfect my improved weather-strip, and add to its efciency by causingit to form an air-tightjoint with the doorsill D, I combine therewith astrip, f, Figs. 5 and 6, of india rubber or its equivalent, which willproject below the edge of the vibrating strip A, and which is securedthereto by means of a binding or stay piece, E, Figs. 5 and 6.

My improved weather-strip ditt'ers from all others chieiy in beinghinged directly to the door, and in being combined with rubber in such amanner as to add greatly to its efli ciency.

Having thus fully described my invention,

what I claim therein as new, and desire to secure by Letters Patent, is

1. The combination and arrangement of a Y single vibrating strip, A,with the recess a, cut in the lower portion of a door, B, by

means of the staples b b, or their equivalents,

substantially in the manner and for the purpose herein set forth.

2. Combining with the lower edge of a vibrating strip, A, Fig. l, astrip ot' india-rubber or other equivalent elastically-yieldingsubstance', substantially in the manner mid strip signed by me this 19thday of May, A.

for the purpose herein set forth. D. 1863.

3. The operating tooth or lug d, when oombined With the sill D andvibrating strip A of a door7 substantially in the marmer and for Inpresence ofihe purpose herein described. D. C. WILEY,
